Can’t go wrong - SIG SAUER OPMOD Romeo5X 1x20mm 2 MOA Dot Compact Reflex Red Dot Sight

The 1/3 cowitness riser aligns perfectly with my iron sights. Mount is very solid. Dot is very crisp, even at full brightness. Unit is light and compact for a streamlined build. Manufacturer warranty is great but this unit seems so solid that I feel it's very dependable. Bought this on recommendation from ex marine friend and very satisfied with purchase.
